Application experiment of DHCP

Experimental requirements:

Pc obtains the IP address through dhcp

The plan is as shown in the picture

The steps of the experiment:

1. Configuration of interactive computer sw1

Sw1 (config) # vlan10, 20 first create vlan10 and vlan20, note here, be sure to create two, connected

Sw1 (config-vlan) # exit

Sw1 (config) # int f1and0

Sw1 (config-if) # switchport mode access

Sw1 (config-if) # switchport access vlan 10 add Port

Sw1 (config-if) # exit

Sw1 (config) # int range f1amp 14-15 set trunk port, configure multiple ports command

Sw1 (config-if-range) # switchport trunk encapsulation dot1q

Sw1 (config-if-range) # switchport mode trunk

two。 Configuration of interactive computer sw2

Sw2 (config) # vlan 10pm 20 you can build only one vlan 20 here.

Sw2 (config-vlan) # exit

Sw2 (config) # int f1and0

Sw2 (config-if) # switchport mode access

Sw2 (config-if) # switchport access vlan 20

Sw2 (config-if) # int f1and14

Sw2 (config-if) # switchport trunk encapsulation d

Sw2 (config-if) # switchport mode trunk

3. Configuration of router R1

R1 (config) # int f0bin1 must first be equipped with IP, that is, the gateway address, which can be applied to one-arm routing.

R1 (config-if) # no shut must open the port first

R1 (config-if) # int f0bin1.10

The number after R1 (config-subif) # encapsulation dot1Q 10 indicates the number of vlan.

R1 (config-subif) # ip add 192.168.10.1 255.255.255.0

R1 (config-subif) # no shut opens subports again

R1 (config-subif) # int f0bin1.20

R1 (config-subif) # encapsulation dot1Q 20

R1 (config-subif) # ip add 192.168.20.1 255.255.255.0

R1 (config-subif) # no shut

R1 (config) # service dhcp starts the dhcp service

R1 (config) # ip dhcp pool vlan10 (vlan10 has no spaces)

^

% Invalid input detected at'^ 'marker.

R1 (config) # ip dhcp pool vlan10 enters vlan10 and allocates dhcp to vlan10's pc server

R1 (dhcp-config) # network 192.168.10.Universe 24

^

% Invalid input detected at'^ 'marker.

R1 (dhcp-config) # network 192.168.10.0 / 24 sets the address pool, with spaces in / 24 and the previous network segment)

R1 (dhcp-config) # def

R1 (dhcp-config) # default-router 192.168.10.1 equipped with gateway

R1 (dhcp-config) # dns-server 2.2.2.2 with dns

R1 (dhcp-config) # exit

R1 (config) # ip dhcp pool vlan20

R1 (dhcp-config) # network 192.168.20.0 / 24

R1 (dhcp-config) # default-router 192.168.20.1

R1 (dhcp-config) # dns-server 2.2.2.2

R1 (dhcp-config) # exit

4. test

Enter the PC side and enter dhcp, which automatically obtains the IP address.
